Under the pressure of the financial crisis, one presidential candidate is behaving like a flustered rookie playing in a league too high. It is not Barack Obama.

Channeling his inner Queen of Hearts, John McCain furiously, and apparently without even looking around at facts, said Chris Cox, chairman of the Securities and Exchange Commission, should be decapitated. This childish reflex provoked the Wall Street Journal to editorialize that "McCain untethered" -- disconnected from knowledge and principle -- had made a "false and deeply unfair" attack on Cox that was "unpresidential" and demonstrated that McCain "doesn't understand what's happening on Wall Street any better than Barack Obama does."

By extension, that means he's also lost the WSJ editorial board (John Fund's head is exploding). That the WSJ equates McCain with Obama is high praise, considering that they have tried to portray as a elitest traitor who would tax multi-billionaires, which is only partially true.

Will continues:

The political left always aims to expand the permeation of economic life by politics. Today, the efficient means to that end is government control of capital. So, is not McCain's party now conducting the most leftist administration in American history? The New Deal never acted so precipitously on such a scale. Treasury Secretary Paulson, asked about conservative complaints that his rescue program amounts to socialism, said, essentially: This is not socialism, this is necessary. That non sequitur might be politically necessary, but remember that government control of capital is government control of capitalism. Does McCain have qualms about this, or only quarrels?

And finishes:

Conservatives who insist that electing McCain is crucial usually start, and increasingly end, by saying he would make excellent judicial selections. But the more one sees of his impulsive, intensely personal reactions to people and events, the less confidence one has that he would select judges by calm reflection and clear principles, having neither patience nor aptitude for either.

It is arguable that, because of his inexperience, Obama is not ready for the presidency. It is arguable that McCain, because of his boiling moralism and bottomless reservoir of certitudes, is not suited to the presidency. Unreadiness can be corrected, although perhaps at great cost, by experience. Can a dismaying temperament be fixed?
